Question

A charge of 35.0 nC is placed in a uniform electric field that is directed vertically upward and that has a magnitude of 4.00 104 V/m.
(a) What work is done by the electric force when the charge moves 0.400 m to the right?
(b) What work is done by the electric force when the charge moves 0.670 m upward?
(c) What work is done by the electric force when the charge moves 2.30 m at an angle of 45.0° downward from the horizontal?
